To all whom it may concern."

Be it known that I, PEROIVAL EVERITT, a subject of the Queen of GreatBritain, residing at London, England, have invented new and usefulImprovements in'or Applicable to Apparatus for Indicating the Force of aBlow, (for which I have obtained patents in the fol.- lowing countries,namely: Great Britain, No. 8,404, dated June 25,1886; France, No.l8l,375, dated February 5, 1887 Belgium, No. 76,296, dated February 9, 1887;Italy, Vol. XXI, No. 21,370, Vol. XLlI, N o. 432, dated March 31, 1887,and Victoria, No. 5,134, dated June 17, 1887,) of which the following isa specification.

This invention relates to an apparatus which will indicate the force ofa blow on a coin or tokenof predetermined value beinginserted in theapparatus. For this purpose I take any suitable apparatus adapted toindicate the force of a blow; but I so construct and arrange theindicating apparatus that it can only operate on the insertion of therequired coin or token.

In order to enable my invention to be fully understood, I will describethe mode ofcarry- 7 ing the same into effect, which I find advantageous,by reference to the accompanying drawings, in which- Figure 1 representsa front elevation of an apparatus constructed and arranged so as toindicate the force of a blow on a coin or token being inserted in theapparatus, accordingto my invention. Fig. 2 represents part of asimilarview to Fig. l, but showing a portion of the front of the casing removedand part of the apparatus in section. Fig. 3 represents a sideelevation, partly in section, of the apparatus; and Fig. 4, a horizontalsection on the line 4 4 of Fig. 1. Fig. 5 is adiagrammatic viewillustrating a slightly-modified form of the apparatus.

Similar letters in all the figures represent similar parts.

A represents the stand, and B the casing, of an apparatus adapted toindicate the force of a blow; B B, rear braces connecting the cas ingwith the stand.

} O is the striking pad or cushion on one end of a tube, D, sliding in afixed tube or guide,

E, and containing the spring F, the degree of compression of whichdetermines the force of the blow, the said parts being of usualconstruction.

a represents the index or pointer of the ap paratus, which is arrangedto move over a graduated scale, b.

c is a loose marking hand or pointer, which, by the index a bearingagainst a pin, a, thereon, is carried along and serves to mark orindicate the force of the blow after the index a has returned to zero,which it does immediately the blowhas been struck.

The index a and loose marking-hand c are respectively attached to ringsd and 6, adapted to rotate upon a boss or short tube, f, forming a guidefor the front end of the sliding tube D.

To the index a, Ijoin alink, g, which is at tached at its other end toone arm, h, of a twoarmed lever, h h, the fulcrum of which is shown atz. The free end of the arm h is bifurcated, as shown in Fig. 2, so thata pin or stud, j, on the end of an arm, k, fixed at Z to the slidingtube D, can pass through it when not prevented by a coin, Z, inserted inthe apparatus, as and for the purpose hereinafter described.

at is a slit, through which the coins for successfully operating theapparatus must be passed, which slit is situated immediately above thespace which normally exists between the bifurcated end of the lever-armh and the pin or stud j, so that the coin will fall into the said space.

n a are pins fixed in the casing B, just below the end of the arm h, andon which the coin rests when first dropped into the machine.

ois aweight on a cord or thelike, 0, attached to the lever-arm 7a,. andworking over a'pulley, p, for the purpose of bringing back the linklever h h, and index a to their normal posistud j. Theblow must then bestruck upon the pad or cushion C, in the manner usual when using anordinary machine for this purpose, and the pad G and the sliding tube Dwill thereby be forced inward to a certain extent, according to theforce of the blow. This extent of movement will, by means of the fixedarm 7., in conjunction with the coin Z, becommunicated to the lever h h(which will be moved toward or into the position shown in dotted linesin Fig. 4) and to the link 9, and thereby to the index a, and loosemarkinghand 0. In thus moving, the lever-armh will describe an arc of acircle, and will therefore slide or carry the coin Z'away from the pinor studj, because this stud is fixed to the tube D, and the arm hchanges its position relatively to this stud, and the coin, being thendeprived of support, will drop within the easing, the pin or stud j thenriding over the curved part or heel of the lever-arm h, as illustratedby the dotted lines in Fig. 4. The pad 0, tube D, and arm in will moveback to their normal position immediately after the blow has beenstruck, and the lever h it, link g, and index a will be drawn back totheir original position (shown by the full lines in Fig. 4) by theweighted cord 0. The loose marking-hand 0, however, will remain in theposition into which it has been moved, and will thus serve to indicatethe force of the blow which has been struck.

It will be understood that the loose marking hand 0 must'be' moved backto zero by hand each time the apparatus is operated, it being providedwith a knob, 1', outside the front of the casing B to allow this to bedone. Should a blow be struck upon the pad or cushion 0 of the apparatuswithout a coin or token having been previously inserted in theapparatus, the pin or stud j, as the fixed arm It moves inward, wouldpass between the bifurcation on the end of the lever-arm h, and wouldtherefore not operate the indicating mechanism.

Instead of the arm It being fixed to the sliding tube D, as hereinbeforedescribed and illustrated in the drawings, I sometimes attach it at anyconvenient point to a pivoted vertical lever or bar, e, arranged to beoperated by the said sliding or movable tube D, as shown in thediagrammatic view at Fig. 5, the spring F being conveniently placed overa guide-rod, f. The other parts of the mechanism would be the same asthose hereinbefore described.

Although I have described and illustrated my invention applied to anapparatus adapted to indicate the force of a blow delivered by aperson's hand, it will be obvious that it is equally applicable to otherforms of apparatus for indicating or' disclosing the force of a blowforexample, to such as may be employed for indicating or disclosing theforce of zublow from a mallet or the like.

In some cases the cushion or pad that re: ceives the blow may be lockedby a suitable retaining device, which is released by a coin being placedin the apparatus; but I find that arrangement not so advantageous asthat hereinbefore described, as it is liable to injury or to causeinjury to the striker when a blow is given while the apparatus islocked.

Handles may be applied to each side of the machine, whereby theoperator, upon placing his bodyagaiustthe pad, may test his strength bypulling on said handles.

1 make no claim to anything shown or described in the application of R.V. Page, Scrial No. 216,665, filed October 19, 1886.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 'In an apparatus for indicating the force of a blow, thecombination, with the frame and with the pad for receiving the blow andwithits reacting spring, of a two-armed lever operated by such pad, acoin receiving and detaining device, a bar carried by the shank or shaftof the pad and operating as set forth, and connections, substantially asdescribed, whereby the coin is caused to operate an index or indicator.

PEROIVAL EVERITT.
